Specification of Letters Patent.

1,174,677. This application filed February 26, 1916. Serial No. 30,560.

To all whom/ it may concern:

Be it known that I, ARGYLE CAMPBELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Hopper-Cars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in hopper cars.

The object of the invention is to provide a hopper car having hinged dumping doors, of efficient and durable construction.

In the drawing forming a part of this specilication, Figure 1 is a side elevation of a portion of a car showing my improvements in connection therewith. Fig. 2 is an enlarged transverse sectional View taken substantially on the line 22 of Fig. 1.`

Fig. 3 is an enlarged detail sectional view taken substantially on the line 3-3 of Fig. 2. And Fig. 4 is a sectional detail taken on the line 4 4 of Fig. 2.

In said drawing, 10-10 denote the side walls of the car, the car being provided with a hopper section intermediate the trucks, the hopper section comprising four hoppers A-A, two on each side of the center sill. The center sill, as shown, comprises a pair of inwardly turned channels 11-11 suitably connected at intervals throughout their length by pressed plates 12. The center sill is covered with a longitudinally extending, inverted V shaped sheclI 13, the latter having vertical portions 14-14 secured to the sides of the built-up center sill, and outwardly and downwardly extending portions 15-15 which form portions of the hoppers. The bottoms proper ofthe hoppers are formed by the longitudinally extending hopper sheets 16, the latter at their upper outer edges having a Vertical portion 17, upwardly and outwardly inclined portion .18, and vertical portion 19 secured to the side of the car. ln order to properly brace the hopper sheets 16 and to also form strengthening members for the car I provide Z bars 20 arranged as clearly shown in Fig. 2. Along their lower edges, the hopper sheets 16 are suitably reinforced by longitudinally extending braces 21, trough shaped in cross section. As clearly shown in Fig. 1, the braces 21 bridge the spaces between the adjacent ends ofthe hoppers. As shown in Fig. 2, each hopperlk is provided with a center dump door 22, the doors 22 being each hinged by three hinges 23 along their upper edges, the hinges being secured to the angle irons 24 which extend longitudinally of the car and on the under side of the portions 15--15 ofthe center sheet. In line with each of the hinges, a bracingclip 25 is extended from the angle iron 24 to the center sill, see Fig. 2. The doors 22 are suitably strengthened along their lower edges by ,having bent flanges 26 and a channel 27 secured thereto, it being understood that the channel extends from one hopper door to the other on the same side of the center sill.

The center dump hopper doors are op- Vbearing brackets 29-29secured to the undex-sides of the hopper sheets 16. From each shaft 28 extend three sets of flexible link connections, each of said connections comprising an elongated hook link 30, short link 31, link 32 and arm 33 formed integrally with the drum on the shaft. The hook shaped links 30 are pivotally connected with the respective channel shaped nicmlicrs 27, between the adjacent ends of the hopper doors, as shown in detail in Fig. 4'. (lppositcly disposed angular members 3l; are secured within the channels, the upstanding arnis of said members 34 forming suitable supports for the pivot pin 35 which passes through the hook shaped link 30. At the ends of the channels 27, corresponding connections are made for the hook shaped links at the ends of the hoppers, as viewed in Fig. 1.

In order to operate the longitudinal shaft 28, I have provided a transversely extending auxiliary shaft 36 mounted in suitable end bearing castings 37-37 on each side of the car, said castings 37 being secured to depending plates 38 which in turn are secured to the side walls of the car. The shaft 36 is .located in the space formed between the adjacent inner ends of the hoppers, see Fig. 3, and beneath the transverse hoppersheets 39-39. The shaft 36 is also supported in suitable brackets 40-40, the latter being riveted to the undersides of the hopper sheets 39. Immediately over each shaft 28, the transverse shaft 36 is provided with a pair of chain winding drums or sheaves 41 and 42. Immediately beneath the sheaves 41 and 42, each shaft 28 is also provided with a pair of winding pulley or sheaves 43--44. Chains are connected to said winding drums, one chain being attached to the drums 41 and 43 and the other chainl to the drums 42 and 44. The winding drums are so arranged that the portions of the chains extending therebetween are perpendicular. The flexible connections between the auxiliary shaft 36 and the longitudinal shafts 28 are duplicated so that as the auxiliary shaft 36 is rotated in one direction, the shafts 28 will be rotated so as tov open the doors 22 and when the shaft 36 is rotated in the opposite direction, the shafts 28 will be rotated so as to close the doors 22. As shown most clearly in Fig. 1, the shaft 36 is provided with a ratchet 45 with which coperates a pivoted pawl 46 and a locking dog 47, the pawl and dog having squared portions 48--48 of the proper size to receive the claw bar or other tool which is employed to rotate the shaft.

By the foregoing arrangement, it will be seen that the center dump doors are all operated simultaneously from the single shaft 36, either in opening or closing. I have shown the auxiliary shaft 36 as extendingV entirely across the car and adapted for operating both shafts 28. This I consider the preferred embodiment as it permits of the operation of all doors simultaneously and from one side of the car. However, it is 4 apparent that instead of using a shaft which extends entirely across the car, short shafts might be employed on each side, each having merely two chain winding drums41 and 42 thereon and adapted for operating' one shaft 28 only. With this construction, the doors on one side of the car would be operated independently of the doors on the other side of the car. Either construction comes within the purview of my invention.

This application constitutes a continuation in part of my prior application 33,237,

. filed June 10, 1915 and upon which Patent rotated in either direction, depending upon the direction of rotation of the auxiliary shaft.

2. In a hopper-dump car having hinged center dump doors on each side of the center sll'l thereof, operating mechanism for all said doors including, a longitudinally arranged shaft on each side of the car, flexible connections from each of said shafts to the adJacent center dump doors, a transversely extending shaft, and iexible link connections between said transversely extending shaft and each of the longitudinal shafts.

3. In a car of the character described, the combination with a car body having hoppers provided with center dump doors, of a longitudinally extending shaft, flexible link connections from said shaft to the hinged doors, a "transversely extending shaft located above said longitudinal shaft, a pair of chain winding drums on each of said longitudinal shafts and corresponding pairs of chain winding drums on said transverse shaft, and chain connections extending between the drums on said shafts.

4. In a car of the character described, the combination with acar body having longitudinally extending -hoppers on each side of the center sill thereof, each'of said hoppers being provided with a hinged center dum door, of a pair of longitudinally extending shafts located on the outer sides of said hoppers, iexible connections from said shafts to the center dump doors, and means for operating said longitudinal shafts simultaneously including, a transversely extending shaft and two sets of chain connections between said transverse. shaft and the longitudinal shafts.

5. In a hopper dump car, the combination with a car body having a built-up center sill, of a longitudinally extending sheet havlng the ridge located above said center sill and provided with outwardly and downwardly extending portions on each side of the center sill, hlnged hopper center dump doors pivoted along their upper edges to the under side of said downwardly and outwardly extending portions of said sheet, longitudinally arranged operating shafts, iexible connections from said shafts to said doors, a transversely extending auxiliary shaft, and flexible connections between the longitudinal and transverse shafts.

6. A car having at each side of its longitudinal center hinged discharge doors, auxillary operating shafts, crank and link connections connecting said shaftsv with the doors for opening andl closing all said doors simultaneously, a manually operative operating shaft and means for imparting reverse motions from said -operating shaft t'o said auxiliary shafts for opening and closing the doors, said means comprising for the doors at each side of the car and for each Iof said auxiliary shafts, a pair of Wheels on said manually operative shaft, a pair of Wheels on the auxiliary shaft and-chains connecting the Wheels on the manually operative shaft with the Wheels on the auxiliary shaft and so disposed that when the manually operative shaft is rotated in one direction, the auxiliary shaft' Will be ro ated to open the doors and when rotated in a reverse direotion, said auxiliary shaft Will have a rel0 Verse rotation imparted to it to compel the closing of the doors. l

In Witness that l claim the foregoing l have hereunto subscribed my name this 16th day of February 1916.
